Wissenschaftler und Ingenieure träumen seit Langem von einem Material, das elektrischen Strom bei Zimmertemperatur ohne Verlust leitet. Vor gut 25 Jahren fanden Forscher mit den Kuprat-Supraleitern (Supraleiter auf Kupfer-Basis) erstmals Stoffe, die bei vergleichsweise hohen Temperaturen supraleitend sind. Diese Eigenschaft hat auch eine neue Klasse von Supraleitern, die erst vor wenigen Jahren entdeckt wurde: Hochtemperatur-Supraleiter auf Eisenbasis. Wissenschaftler des Paul Scherrer Instituts in Villigen haben zusammen mit chinesischen und deutschen Forscherkollegen nun neue Erkenntnisse zu dieser Klasse von Supraleitern gewonnen. Die experimentellen Ergebnisse aus der Grundlagenforschung deuten darauf hin, dass magnetische Wechselwirkungen für das Phänomen der Hochtemperatur-Supraleitung von zentraler Bedeutung
